Mesothelioma and Asbestos

Asbestos is a group of naturally occurring minerals known to be carcinogenic. Asbestos releases strong, microscopic, flexible fibers that can be separated into thin threads that may injure the protective linings surrounding the body's organs.  Asbestos is a naturally occurring mineral and can be found in dust and rocks in certain parts of the United States as well as different parts of the world.

In the past, asbestos was added to a variety of products to strengthen them and to provide heat insulation and fire resistance.  Asbestos has been used in many products including cement, brake pads, roof shingles, textiles, insulation, floor tiles, door gaskets, soundproofing, patching compounds, fireproof gloves and ironing board covers.  Most use of asbestos stopped after 1989, but it is still used in some products.  Experts have linked the drop in use to the fact that the rate of development of mesothelioma is no longer increasing.

People who are exposed to asbestos for just a short period of time (few weeks) or even to a small amount may be at risk. In particular, people working with asbestos and their family members or those who live with them develop mesothelioma.

Working with asbestos is the major risk for causing mesothelioma.  A history of exposure to asbestos at work is reported in about 70 to 80 percent of all cases although.  People who may be at risk for occupational asbestos exposure include some miners, factory workers, insulation manufacturers, railroad workers, ship builders, gas mask manufacturers, and construction workers, particularly those involved with installing insulation. 

Mesothelioma has also been reported in individuals without any knowledge of asbestos exposure.  Several studies have shown that family members of people exposed to asbestos at work have an increased risk of developing mesothelioma, because asbestos fibers can be carried home on the clothes of the workers.

If tiny asbestos particles float in the air, they may be inhaled or swallowed, and can cause serious health problems.  Exposure to asbestos also increases the risk of lung cancer and other cancers, such as that of the larynx and kidney.
